Anti-cheat

Games with kernel-level anti-cheat (many online shooters) won't work, and Superposer tells you before you install. Superposer never strips, emulates or bypasses anti-cheat or DRM, and games always start through the real Steam client. Some games with anti-cheat can still be played offline.

What decides whether a game works

  • The graphics API: DirectX 11 and 12 games mostly use Apple's D3DMetal (64-bit only); DXMT and WineD3D cover others, including older DirectX versions.
  • Anti-cheat and publisher launchers can block a game.
  • Your Mac's chip and memory matter for demanding games.

Inside the app, each game shows a verdict with the evidence behind it before you install, and the Test button checks it on your own Mac. More in Help › Compatibility.

How we rate games

Every game has one page that brings together three kinds of evidence. They are ranked in this order, and when they differ the higher one decides:

  1. Players. Results testers shared from the app on a Mac (anonymous, one per install per game), and ProtonDB reports from players on Linux and Steam Deck, which are only a starting point for a Mac.
  2. Superposer tests. Automated runs on real Macs: the game launches, draws real frames and reaches its menu.
  3. Predicted. The game's Steam Deck rating, which says how it fares on a similar stack.
  • Verified means Superposer's own recent tests passed on several different Macs and players do not report it as broken. These pages show the macOS versions and kinds of Mac it passed on.
  • Should work means recent reports are good but nobody has confirmed the game on enough Macs yet. Works with issues means players report bugs or needed tweaks; the main issues are listed. Doesn't work means the evidence rules it out today, usually anti-cheat that refuses Wine-based tools.
  • Not enough data means there is nothing solid to say yet. Most Windows games do run, so it can be worth a try.
  • A confident estimate, not a headcount: a game needs several different players before a statement is made, and it takes a run of bad reports, not one, to move it down. One bad vote can never flip a game.
  • Hard blockers cap the result: kernel-level anti-cheat that refuses Wine and Proton keeps a game out of the top groups. Only a run of ours that passes outranks it.

The estimates are rebuilt weekly and signed (the data, ODbL 1.0). An estimate is not a promise: results depend on the game's version, your Mac and the runtime.
